[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will further describe the technical solutions in the embodiments of the present application in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application but not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0017] As Figure 1 the present embodiment provides a kind of initial rainwater sedimentation tank integrated with flow distribution, sedimentation and reuse, and the flow distribution area 1, reuse area 2 and sedimentation area 3 are separated by partition wall in the sedimentation tank, the flow distribution area 1 is equipped with inlet 4, reuse area 2 is equipped with outlet 5, first valve 6 is equipped on the partition wall between the flow distribution area 1 and the sedimentation area 3, second valve 7 is equipped on the partition wall between the flow distribution area 1 and the reuse area 2, and third valve 8 is equipped on the partition wall between the reuse area 2 and the sedimentation area 3.
[0018] The pool bottom of the sedimentation area 3 is provided with a slope of 5‰, and the side far from the flow distribution area 1 and the reuse area 2 is the lowest point.
[0019] The sludge collecting pit 9 is arranged at the lowest point of the pool bottom of the sedimentation area 3, and the sludge collecting pit 9 is located at the corner of the sedimentation area 3.
[0020] Preferably, the sludge discharge pump 10 is installed in the sludge collecting pit 9.
[0021] The water inlet 4 is provided with a rainfall sensor, the first valve 6, the second valve 7 and the third valve 8 are all controlled by an electric control of a hoist, the rainfall sensor monitors rainfall, and the electric control of the hoist is linked. The rainfall sensor and the gate hoist are linked and controlled, which saves the labor cost of manually opening and closing the gate during rainfall, facilitates operation and management, and compared with the traditional control mode of collecting only the previous 15-30 minutes, the initial rainfall can be maximized collected for reuse in the case of heavy rain and light rain, and the port water cost is saved.
[0022] It should be noted that the linkage is controlled by a controller, the signal of the rainfall sensor is transmitted to the controller, and the hoist is also connected with the controller.
[0023] Working principle and key points:
[0024] In the design of the sedimentation tank, the diversion area 1 and the reuse area 2 are separated in the sedimentation tank. The rainwater in the port area is collected through the rainwater pipe network, enters the diversion area 1 of the sedimentation tank first, the early initial rainwater and daily ground washing wastewater enter the sedimentation area 3 through the first valve 6, the rainfall is monitored by the rainfall sensor, and the electric control of the hoist is linked. When the set rainfall is reached, the first valve 6 is closed, the second valve 7 is opened, and the clean rainwater in the later period flows over the reuse area 2 to the nearby water body. The sewage in the sedimentation area 3 is preliminarily treated to remove most of the particulate matter, and the third valve 8 is opened at this time. The supernatant after sedimentation enters the reuse area 2 for reuse.
[0025] This design integrates the sedimentation tank, the gate well and the reuse tank, which can greatly save engineering investment and land resources. At the same time, a 5‰ slope is set at the bottom of the sedimentation tank, and a water collecting pit 9 is set at the corner. A sludge pump 10 is installed in the water collecting pit 9. Daily sundries and sludge are deposited in the water collecting pit 9, which can be pumped out by the sludge pump 10. Daily maintenance is facilitated, and labor cost is saved.
